I am happy with all things except sound: the SONY TV I have connected via HDMI (or via DP and DP to HDMI active converter) does not work at all.
I need help with the settings for the device.hints file in /boot. I have given up after reading the man page for snd_hda! I can supply all the info from dimes if required. Thanks for anybody who can help!

Maybe you can help but I cannot see any HDMI pcm device when quering the system!
Thanks again.

Hmm ... it seems there is only analog output, there is no HDMI output listed.

mixer values looks ok.

Exactly, that's a starting point.

If the module snd_hda is loaded, it might means support for you card is absent/incomplete (I'm not really an expert about audio), I was suspecting it was not the default, but didn't expect it not listed/recognzed at all.

That's something that I would need to research myself ... I will post back when/if I will have useful info.
